Abstract

A process for treating the coking sewage by culturing and naturalizing the nitrifying bacteria and the denitrifying bacteria is disclosed. The process for culturing and naturalizing the denitrifying bacteria includes filling the mixed liquid from aerobic pool into anaerobic pool, flowing the supernatant from depositing pool back into anaerobic pool, inoculating denitrifying bacteria, culturing and naturalizing. The process for culturing and naturalizing the nitrifying bacteria includes introducing the nitrogen-contained sewage to aerobic pool, culturing naturalizing.

Description

technical field

[0001] The invention relates to a sewage treatment method, in particular to a method for treating coking plant sewage by using the original common activated sludge to cultivate domesticated nitrifying and denitrifying bacteria. Background technique

[0002] Biological denitrification is the use of chemical principles to remove ammonia nitrogen (NH 4 + ) After nitrification and denitrification reactions, the ammonia nitrogen is finally converted into harmless nitrogen and released. Nitrification is the overall process of converting ammonia nitrogen into the nitrate form. which is <chemistry num="001"> <chem file="200310111176_cml001.xml" / > < / chemistry> , the reaction is completed with the help of heterotrophic bacteria and autotrophic bacteria. In the natural environment, a large amount of nitrate and nitrifying bacteria are produced by heterotrophic bacteria. These two types of organisms need to obtain energy from the oxidation of inor...
